JUMO exTHERM S200
Surface-mounted thermostat for ATEX and SIL applications
The surface-mounted thermostat is available as a single or double thermostat with capillary or rigid thermowell. A microswitch is used as the electrical switching element. The device operates according to the principle of liquid expansion. It is available as a temperature monitor, safety temperature monitor, and safety temperature limiter. Additional thermowells allow use in zone 0.
